Build and deploy a declarative agent in Copilot Studio with prompts for Microsoft Copilot, Teams and Power Platform

Key insights

  • Declarative agents for Microsoft 365 Copilot: Elaiza Benitez demos building an agent that embeds clear instructions, tools, and connectors so Copilot answers device-related questions inside Microsoft 365 apps.
    She shows how declarative manifests define an agent’s mission, behavior, and conversation flow.
  • Key features: Agents use a low-code/no-code approach, can leverage GPT-5 for advanced reasoning, and connect to enterprise data like SharePoint and Dataverse to provide context-aware, automated assistance.
    They improve workflows and reduce manual steps for teams.
  • Deployment steps: Create the agent in Copilot Studio, add an AI prompt as a tool, configure knowledge connectors and actions, then test and publish.
    Elaiza follows the sequence: create agent → add prompt → update instructions and test → publish.
  • Publishing and sharing: You can publish agents to Microsoft 365 Copilot and Microsoft Teams, share them tenant-wide or with specific groups, or export an app package for Teams deployment.
    Publishing controls let administrators limit access and scope.
  • Developer tools: Use Visual Studio Code extensions, the Model Context Protocol (MCP), and Azure AI Foundry to connect external services and custom models for richer capabilities.
    These tools speed development and allow domain-specific tuning.
  • Testing, security, and governance: Test agent instructions in Copilot Studio, then publish; agents respect Microsoft Information Protection labels and integrate with Microsoft Purview to keep data compliant.
    Regular updates and access controls maintain safety and accuracy.

Introduction

The YouTube video from Microsoft follows Elaiza Benitez as she walks viewers through deploying a declarative agent for Microsoft 365 Copilot. In the demo, Benitez uses Copilot Studio to build an agent that answers device-related questions, adds an AI prompt as a tool, and publishes the agent so it is available in both Copilot and Teams. As a result, the video serves as a practical, step-by-step guide for organizations looking to customize Copilot behavior without heavy engineering work. Furthermore, the recording includes chapter markers that make it easy to navigate the main steps of the process.

Importantly, the presentation emphasizes low-code creation and enterprise integration, showing how declarative manifests define an agent’s mission, tools, and knowledge sources. Thus, viewers can see both the user interface flow in Copilot Studio and the conceptual pieces that power the agent. In addition, the video highlights resources such as the Agent Academy for continued learning and experimentation. Consequently, the clip aims to make advanced AI customization accessible to business and IT teams alike.

Step-by-step walkthrough in the video

The demo begins with an explanation of what a declarative agent is and why organizations would create one, and then progresses to a live build in the studio. Benitez demonstrates creating the agent, adding a custom prompt as a tool, and updating the agent’s instruction set so it handles device troubleshooting questions accurately. She then tests the agent interactively inside Copilot Studio, showcasing how small instruction tweaks change responses in real time. After validation, the final step published the agent to both Microsoft 365 Copilot and Microsoft Teams with options for sharing and access control.

The video also outlines practical testing steps and common edits, which helps non-developers understand how to iterate on behavior without rewriting code. In particular, Benitez shows how to refine conversation starters and update connectors to enterprise knowledge stores during testing. Moreover, the walkthrough touches on publishing choices like tenant-scoped access versus broader distribution, giving administrators clear next steps after development. Thus, the sequence balances hands-on guidance with governance considerations.

Key features and advantages explained

The presenter highlights several advantages that emerge from this approach, starting with low-code setup through Copilot Studio and visual tools that lower the barrier to entry. In addition, the video notes integration with enterprise knowledge sources such as SharePoint - Lists and Microsoft Dataverse, which boosts contextual accuracy and usefulness for business workflows. Furthermore, the demonstration references the platform’s support for advanced models like GPT-5, which can improve multi-turn reasoning and more complex task handling where needed. Together, these elements enable tailored assistants that align with organizational processes.

Security and compliance receive attention as well, since the agents respect organizational data controls and label policies through integrations with tools like Microsoft Purview and MIP labels. Consequently, the video reassures viewers that customization does not require sacrificing governance, especially when agents access sensitive content via connectors. In addition, developers and admins can use Visual Studio Code extensions and the Model Context Protocol to extend functionality while maintaining enterprise controls. Therefore, the platform attempts to bridge ease of use with robust security capabilities.

Finally, the recording points out flexible publishing and developer tooling as practical benefits, allowing distribution to Teams, Copilot Chat, and even preview channels for external messaging. This flexibility supports both internal productivity scenarios and customer-facing experiences when appropriate. However, the video stresses that administrators should plan sharing rules carefully to avoid unintended exposure. Overall, the feature set encourages broad adoption while underscoring the need for governance.

Tradeoffs and practical challenges

Despite the advantages, the video also implies several tradeoffs that organizations must weigh, such as balancing ease of customization against the risk of inconsistent agent behavior if guidance is loosely defined. For instance, low-code tools speed creation but may obscure nuanced model behavior that requires careful prompts and constraints to avoid hallucinations or off-topic answers. Moreover, integrating many external data sources increases contextual richness, yet it also complicates compliance checks and raises authentication complexity. Thus, teams must decide how far to push connectivity versus how tightly to lock down data flows.

Another challenge discussed is model governance and testing; while GPT-5 capability can improve outcomes, it can also make debugging harder when agents take unexpected reasoning paths. Accordingly, the video suggests iterative testing and clear instruction management inside agent manifests to keep responses predictable. In addition, administrators face deployment choices—tenant-wide publishing simplifies access but magnifies governance risk, whereas restricted distribution reduces exposure but limits adoption speed. Therefore, planning deployment scope and monitoring usage are critical ongoing tasks.

Operationally, the demo surfaces real-world considerations like authentication for connectors, versioning of agent definitions, and the need for multidisciplinary collaboration between IT, security, and business teams. Meanwhile, the video encourages leveraging resources such as training modules and documentation to build internal skills for maintaining agents. Ultimately, success depends on aligning technical, security, and business objectives rather than treating the agent as a one-off project.

Deployment considerations and conclusion

In closing, the YouTube video from Microsoft delivers a clear, practical guide to building and publishing a declarative agent for Microsoft 365 Copilot, with useful demonstrations of creation, testing, and publishing workflows. It emphasizes that declarative manifests and Copilot Studio enable powerful, low-code customization while also calling attention to governance and testing needs. Therefore, organizations should invest time in prompt engineering, connector configuration, and access planning before rolling agents into production. In this way, they can unlock tailored assistance while minimizing operational and compliance risks.

For editorial teams and readers, the video is both an instructional resource and a prompt to consider policy and process as integral parts of AI deployment, not afterthoughts. Consequently, the recording is best used alongside governance frameworks and training programs to ensure agents deliver consistent, secure, and valuable experiences. Finally, the presentation makes it clear that with careful planning and iterative testing, declarative agents can extend Copilot’s value across many enterprise scenarios.
